IMPROVEMENT IN ROOFI-NG-SGAFI'OLD.

TO ALL WHOM IT MAY CONCERN:

Be it known that. I, PETER. RICHMOND,/of Aberdeen, in the county ofOhio, and-in the State of Indiana, have invented certain new and usefulImprovements in Roofing-scaffold; and do hereby declare that the follow#ing is a. full, clear, and exact description thereof, reference beinghad tothe accompanying drawings, and to the lettersA of reference markedthereon.

In the annexed drawings, making part of this specification, A Arepresent two pieces of thick board or` narrow scantling, with theirupper ends bevelled at about an angle of forty-five degrees. 'Thesepieces are placed parallel to each other, and at a suitable distanceapart, and are connected by means of a board, B, secured fast to theirhevelledA edges. A frame, C, connected by cross-pieces Fand G, is placedbetween the two pieces A A, and connected to them by means of bolts Eand D. v The frame-pieces C C are provided with a series of holes, a a,for the bolt I), so that the frame can be adjusted, with reference tothe pieces A A, to suit the pitch ofthe roof upon which this bracket isAto be used. Instead ol' the frame C C, I inlay bring the pieces A Aclose enough together to embrace a single piece of soantling, II, as-seen in Figure 4. Two bolts will connect the scantling H to thepiecesA, as in the other case, the outer or lower bolt having,r severalholes'to regulate the pitch of the scaffold. Metallic plates I I,provided with suitablepoints, are secured toJ the lower ends of theframe-pieces C C or H, and to the under side of the boards B B at eachend'.

When this scaffold is placed upon the roof of' a building, the points ofthe plates I I catch linto the said roof, and station the scaffold atany desired point. Two or more of these scatfolds may be used upon aroot` in line with each other, and a Scofield-board laid from one to theother, furthe purpose of forming a long scaffold.

,Having thus fully described my invention, what I claim-as new, anddesire to secureby Letters Patent, is-

The side pieces A A, vplat-form; B, plates I I, and the frame C C orseantling H, for forming a scaffold, the several parts being constructedand used substantially-as and for the purpose set forth. p

In testimony that I claim theforeroing, I have hereunto set my hand,this 4th da);r of September, 1867.
